Check out a posthumous Doe B single, "Betta Kno It."

We already saw Doe B appear on Kevin Gates' single "Amnesia" which was just one of several tracks he's been featured on since his death. Today, Hustle Gang has let go a new single and solo cut from Doe.

The stunting track, "Betta Kno It", is produced by Karltin Banks, and comes with the promise of a new Doe B album on the way. Cop the single on iTunes.
